Around a decade ago, Samsung launched the Galaxy S II which is still remembered as a masterpiece. The device came equipped with a 4.27-inch Super AMOLED Plus display and the most powerful smartphone processor Exynos 4 Dual (4210) on the market at the time. Besides, it also became the first handset featuring a convenient flashlight function.

In the software department, the company shipped the Galaxy S II with Android 2.3 “Gingerbread” out of the box. Further, it has upgraded to Android 4.1.2 “Jelly Bean” and completed its major update lifecycle. Also, the Galaxy S II is no longer eligible to get any type of software update from Samsung as it is now a 10 year older phone.

Thanks to the group of XDA members for bringing the Galaxy S II users a way to unofficially install the Android 11-based LineageOS 18.1. Users can now get all the bells and whistles of the Android 11 version on this masterpiece unofficially. If you don’t know, LineageOS is a custom operating system for smartphones and tablets which is based on Android.
